BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a hanging device, more particularly to an adjustable hanging device.

2. Description of the Related Art

Typically, flat panel displays are hung on a wall surface with the use of a conventional hanging device, such as screw means.

The conventional hanging device is disadvantageous in that, if the flat panel display is not leveled upon hanging, the position of the conventional hanging device needs to be adjusted. The adjustment of the position of the conventional hanging device involves unfastening and re-fastening thereof, which is inconvenient, error prone, and time consuming.

Therefore, the object of the present invention is to provide an adjustable hanging device that is capable of overcoming the aforesaid drawback of the prior art. According to the present invention, an adjustable hanging device, which is adapted to hang an object on a wall surface, includes a bracket, a screw rod, and a carriage. The bracket is adapted to be mounted on the wall surface. The screw rod extends into the bracket, and is operable so as to rotate relative to the bracket. The carriage threadedly engages the screw rod, is adapted to support the object, and is movable along the screw rod when the screw rod is operated so as to adjust the position of the object on the wall surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 3, the preferred embodiment of an adjustable hanging device 100 according to this invention is shown to include a bracket 2, a screw rod 3, and a carriage 4.

The adjustable hanging device 100 is adapted to hang an object 12 (see FIG. 4) on a wall surface (W) (see FIG. 5). In this embodiment, the object 12 is a flat panel display.

The bracket 2 is adapted to be mounted on the wall surface (W), and includes first and second bracket parts 21, 22. The first bracket part 21 defines a carriage-receiving space (S), and includes a base wall 211, first and second lateral walls 212, 213, and top and bottom walls 214, 215, which cooperatively confine the carriage-receiving space (S). A hang ring 216 is provided on the top wall 214 of the first bracket part 21. The first bracket part 21 further defines an opening (O) that is in spatial communication with the carriage-receiving space (S). The second bracket part 22 serves to cover detachably the opening (O) in the first bracket part 21. The top wall 214 of the first bracket part 21 is formed with a hole 210 that is in spatial communication with the carriage-receiving space (S).

The screw rod 3 extends into the bracket 2, and is operable so as to rotate relative to the bracket 2, as indicated by the arrow (X) in FIG. 3. In particular, the screw rod 3 has an enlarged head 31 that is disposed externally of the carriage-receiving space (S) and that is anchored to a periphery of the hole 210 in the top wall 214 of the first bracket part 21, and a shank 32 that extends integrally from the enlarged head 31 of the screw rod 3 and into the carriage-receiving space (S) through the hole 210 in the top wall 214 of the first bracket part 21. The shank 32 of the screw rod 3 has a threaded portion 321 that is separate from the first bracket part 21, i.e., the threaded portion 321 is free of a threaded connection with the first bracket part 21. As such, rotation of the screw rod 3 relative to the bracket 2 does not result in axial movement of the screw rod 3. The shank 32 of the screw rod 3 further has a non-threaded portion 322 disposed between the enlarged head 31 and the threaded portion 321 of the screw rod 3. In this embodiment, the non-threaded portion 322 of the shank 32 of the screw rod 3 is formed with an annular flange 33 that projects radially therefrom. The enlarged head 31 and the annular flange 33 of the screw rod 3 cooperatively define an annular groove 30 therebetween. The periphery of the hole 210 in the top wall 214 of the first bracket part 21 is received in the annular groove 30 so as to permit mounting of the screw rod 3 on the bracket 2.

The carriage 4 is disposed in the carriage-receiving space (S), threadedly engages the threaded portion 321 of the screw rod 3, is adapted to support the object 12, and is movable along the threaded portion 321 of the screw rod 3, as indicated by the arrow (Y) in FIG. 2, when the screw rod 3 is operated. In particular, the carriage 4 includes first and second carriage parts 41, 42, and a threaded rod 43. The second carriage part 42 extends transversely from the first carriage part 41 in a direction away from the top wall 214 of the first bracket part 21. It is noted that the carriage 4 is U-shaped, and includes a first arm, a second arm parallel to the first arm, and a cross arm that interconnects the first and second arms. The first arm serves as the first carriage part 41, whereas the cross arm serves as the second carriage part 42. The first carriage part 41 is formed with a first inner thread 410. The threaded portion 321 of the shank 32 of the screw rod 3 engages threadedly the first inner thread 410 of the first carriage part 41 of the carriage 4. The second carriage part 42 is formed with a second inner thread 420. The second bracket part 22 is formed with an elongated hole 220. The threaded rod 43 has a first end portion 431 that engages threadedly the second inner thread 420 of the second carriage part 42 of the carriage 4, and a second end portion 432 that extends from the first end portion 431 of the threaded rod 43, and that has a free end distal from the first end portion 431 of the threaded rod 43 and formed with an enlarged head. It is noted that the second end portion 432 of the threaded rod 43 extends outwardly of the carriage-receiving space (S) through the elongated hole 220 in the second bracket part 22, and is adapted to hang the object 12. It is also noted that the elongated hole 220 in the second bracket part 22 has a sufficient length to permit movement of the threaded rod 43, as indicated by the arrow (Z) in FIG. 3, when the screw rod 3 is operated.

Referring to FIGS. 4 and 5, as an application of the adjustable hanging device 100 of this invention, the object 12 is hung on the wall surface (W) with the use of two adjustable hanging devices 100. Each of the adjustable hanging devices 100 is first mounted on the wall surface (W) by means of a screw fastener 5 that passes through the hang ring 216 of a respective one of the adjustable hanging devices 100 and that is fastened to the wall surface (W). The object 12 has left and right end portions 121, 122, each of which is formed with a hanging groove 120, 120′. The object 12 is then hung on the wall surface (W) such that the enlarged head of the second end portion 432 of a respective one of the threaded rods 43 is disposed in and is anchored to a periphery of a respective one of the hanging grooves 120, 120′. Upon hanging the object 12, and if the object 12 is not leveled, that is, if one of the left and right end portions 121, 122 is higher or lower than the other, each of the screw rods 3 may be operated to raise or lower the vertical position of the left and right end portions 121, 122 of the object 12 on the wall surface (W) until the object 12 is leveled.

It is noted that the adjustable hanging device 100 may be mounted on the wall surface (W) such that the screw rod 3 is oriented to extend horizontally. As such, when used in the aforementioned application of the adjustable hanging device 100 of this invention, each of the screw rods 3 may be operated to adjust the horizontal position of the object 12 on the wall surface (W).
